TPD4160 - Security: physical and financial: Financial Security: review of guarantee levels
You should monitor the use of the guarantee to ensure that the level of cover is sufficient given the risks involved and trader reliability.
The principal to a guarantee may request a review of the guarantee level at any time. They may seek reductions on the grounds of changes in levels of production, number and size of movements, or for similar reasons. New or recent traders may also seek a reduction on the grounds that they now qualify as established traders with a good record (see sections TPD4080 to TPD4140).
You should discuss changes to guarantee levels with the CCM to ensure equity of treatment. Guarantee levels may not be reduced below the minimum amount.
